Which of my Sketch plugins will work with Studio?

Studio is entirely separate product from Sketch, and as such does not support Sketch plugins.

That being said, an extensive app ecosystem is in the works for Studio. We believe in empowering our customers and developer communities with the ability to augment their workflows in powerful ways with forthcoming Studio Apps. Studio Apps are our vision for a thriving, vibrant third-party eco system to be launched in late 2018.
